[RESOLVED] Button Problem

[stevejenks]

So i have a little problem, I'm creating a multiple choice quiz in AS3. At the minute the user is free to skip the question by clicking the next question button.

What I'm trying to do is to hide the button and then have it re-appear once the user has clicked the correct answer. I know I'm going wrong somewhere but any help would be massively appreciated.

I've put the code relating to the button in bold to highlight the problem.

Thanks for your time.

stop();

messageBox.text = "";					// Clears the Response box
var correctAnswer:String = "2 Minutes";	// Sets correct answer for comparison
var userAnswer:String;					//  with value from radio button group.
var rbg:Object = rbtwo.group;		// Get the name of the radio button group from the first button.

next_btn.enabled = false;

next_btn.addEventListener(MouseEvent.CLICK, changeQuestion);

btnCheck.addEventListener(MouseEvent.CLICK, checkAnswer);

function checkAnswer(evt:MouseEvent):void {
	userAnswer = String(rbg.selectedData);
	if (userAnswer == correctAnswer) {
	   messageBox.text = "Yes, " + userAnswer + " is the correct answer!";
	   next_btn.enabled == true;
	}
	else {
	   messageBox.text = "No, " + userAnswer + " is incorrect. Try again.";
	}
}

function changeQuestion(event:MouseEvent):void {
	if (userAnswer == correctAnswer) {
		next_btn.enabled == true;
	}
	else{
		next_btn.enabled = false;
	}
}

next_btn.addEventListener(MouseEvent.CLICK, next15Click);

function next15Click(event:MouseEvent):void
{
       gotoAndPlay(21);
};

Anybody have any ideas?

Im new to AS3 so i understand my nextquestion eventhandler may be totally wrong.

But a little guidance would be greatly appreciated.

You are using double-equals (==) instead of assignment equals (=). This results in a rather useless comparison and a boolean result instead of actually changing the value of next_btn.enabled.

Thanks for the help.

I've taken out my changeQuestion event holder as I presumed it wasn't doing anything.

Basically, this code returns no errors but the button remains on stage the whole time.

Any ideas what i'm missing?

Thanks

import flash.display.MovieClip;
stop();

messageBox.text = "";				
var correctAnswer:String = "2 Minutes";
var userAnswer:String;					
var rbg:Object = rbtwo.group;		

next_btn.enabled = false;

btnCheck.addEventListener(MouseEvent.CLICK, checkAnswer);

function checkAnswer(evt:MouseEvent):void {
	userAnswer = String(rbg.selectedData);
	if (userAnswer == correctAnswer) {
	   messageBox.text = "Yes, " + userAnswer + " is the correct answer!";
	   next_btn.enabled = true;
	}
	else {
	   messageBox.text = "No, " + userAnswer + " is incorrect. Try again.";
	}
}

next_btn.addEventListener(MouseEvent.CLICK, nextframe);

Oh, if you actually want the button off stage, you'll have to remove it rather than just set it to enabled = false.

import flash.display.MovieClip;
stop();

messageBox.text = "";				
var correctAnswer:String = "2 Minutes";
var userAnswer:String;					
var rbg:Object = rbtwo.group;		

removeChild(next_btn);

btnCheck.addEventListener(MouseEvent.CLICK, checkAnswer);

function checkAnswer(evt:MouseEvent):void {
	userAnswer = String(rbg.selectedData);
	if (userAnswer == correctAnswer) {
	   messageBox.text = "Yes, " + userAnswer + " is the correct answer!";
	   addChild(nextBtn);
	}
	else {
	   messageBox.text = "No, " + userAnswer + " is incorrect. Try again.";
	}
}

next_btn.addEventListener(MouseEvent.CLICK, nextframe);
